Re-purchased quilt design software today (apparently 15 year old software doesn't run on windows 8), and started playing around. The last one was a total accident (struggling with the block rotating and flipping tools) but I kind of love it. The third and fourth are inspired by this block and will pop more than it seems in these mock ups. The first and second are more traditional so might match the retro house better, but very undecided at the moment. And the heavy lifter hasn't had a chance to weigh in. And I've never tried the kaliedescope block (1st image) so if it's annoying it will have to be excluded.
